150 4stroke ser# below.
I installed a new Fuel sender and it worked great when it was on the analog gauge and analog (conversion)helm harness.
Analog gauges are now gone as is that harness. Replaced with a J box and SC1000 Tach and Speedo.
I installed the fuel/paddle wheel harness. RED "fuel 1" (pos) wire to the pos on the sender. The neg sender wire goes straight to the neg side of the engine starting battery. All per the instructions and double checked. The 6 pin wire harness plug is connected to the plug under the cowl. No paddle wheel installed (that plug is covered with the supplied cover.)
Went to the gas station with the fuel calibration instructions in hand. Set it for 60 gals total. Went into the default or Add fuel mode and hit Add. I added 15 gals (for the 1/4 step) hit "save". Added 15 more (for 1/2 step) hit "save". Window said something about calibration failed reading taken from "Default". I Stopped. I have since changed the setting back to "Default" so it would take it's reading via the smartcraft system. SC100 gauge reads empty (it does move a little when power is applied or I reset via either tach or speedo). The fuel bar in the speedo shows low fuel and empty. The fuel reading on the tach shows 0. I fired up the motor (yes with water) and all the sc100 gauges work INCLUDING the FUEL FLOW meter. I raised the idle slightly and the flow gauge corresponded correctly.
With 30 gals of gas one would think it should read something...
What is my next step? Is their something in the computer that needs to be changed?
